[I]t won 15 out of 16 races in the 1988 season, with Ayrton Senna and Alain Prost behind the wheel. On six occasions the MP4/4 qualified first and second with a margin of a second or more, and at Monaco, Senna was 2.6 seconds faster than his nearest non-McLaren rival. But, even more amazing is this incredible pace was at no detriment to reliability. The MP4/4 retired just four times, two of which were a result of crashes.
